Get Your Sleep, or Get Fat

A new study has found that one night of poor sleep could equal six months on a high-fat diet, according to newswise.com. OMG.

New research finds that one night of sleep deprivation and six months on
a high-fat diet could both impair insulin sensitivity to a similar
degree, demonstrating the importance of a good night’s sleep on health.

When the body becomes less sensitive to insulin (i.e., “insulin-resistant”), it needs to produce more insulin to keep blood sugar
stable. This may eventually lead to Type 2 diabetes, a disease where the
body’s insulin response doesn’t work properly and there is too much
sugar in the blood. Diabetes is associated with a number of serious
complications, including heart disease. Individuals with obesity are
more likely to develop insulin resistance and subsequently, diabetes.

“Research
has shown that sleep deficiency and a high-fat diet both lead to
impaired insulin sensitivity, but it was previously unknown which leads
to more severe insulin resistance,” says Josiane Broussard, PhD, Cedars-Sinai Medical Center in Los Angeles, CA . “Our study
suggests that one night of total sleep deprivation may be as detrimental
to insulin sensitivity as six months on a high-fat diet. This research
demonstrates the importance of adequate sleep in maintaining blood sugar
levels and reducing risk for metabolic diseases like obesity and
diabetes.

"One night of sleep deprivation and six months of a high-fat diet
both reduced insulin sensitivity by a similar degree in canines;
however, there was no additive effect of sleep loss and high-fat diet,”
adds Dr. Broussard. “This may suggest a similar mechanism by which
both insufficient sleep and a high-fat diet induce insulin resistance.
It could also mean that after high-fat feeding, insulin sensitivity
cannot be reduced further by sleep loss.”

In addition to impaired
insulin sensitivity, sleep deprivation can lead to increased food intake
and overall increased risk for metabolic diseases.So get your sleep.

For all of you out there who got straight A's and scored high on your SAT (if you can remember back that far!), it doesn't necessarily mean that you can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face- matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people’s visual ability and that these variations are not associated with individuals’ general intelligence, or IQ.

“People may think they can tell how good they are at identifying objects visually,” says Isabel Gauthier, David K. Wilson Professor of Psychology at Vanderbilt University, who headed the study. “But it turns out that they are not very good at evaluating their own skills relative to others.”
In the past, research in visual object recognition has fo…

Researchers from Leeds Beckett University are challenging the myth that extreme sports enthusiasts push themselves to the max and take risks no matter what the consequences.

Wingsuit flying is a relatively new parachute sport which involves a specifically designed jumpsuit that facilitates forward motion and directional control, according to newswise.com. It is considered the most dangerous parachute sport as it involves flying close to structures at speeds of over 200 mph, where a mistake or accident would most likely result in death, the web site maintains.

“When you think of the people involved in such extreme sports, you tend to think of risk takers who push themselves to the limit," says Dr Eric Brymer, a Reader in the Carnegie School of Sport. &quo…

In any event, a new report investigates what effect they have on pretty much the last place you'd expect them. The workplace. Or, at least, the places I worked. In fact, sending and receiving emojis in the workplace could have an impact on productivity and innovation in the workplace, according to newswise.com.

University of Delaware management professor Kyle Emich has explored the effects of emotions on teams and performance and is now taking on what effect, if any, they have on innovation and productivity.
"In our lab, we normally induce emotional states by showing people happy or sad video clips or pictures," he tells newswise.com. "For example, we…
